Description
M/A-COM’s SW-442 is a GaAs monolithic switch in
a low cost SOT-26 surface mount plastic package.
The SW-442 is ideally suited for applications where
very low power consumption, low insertion loss and
very small size are required.
Typical application is in dual band systems which
require switching between small signal components
such as filter banks, single band LNA's, converters
etc. The SW-442 can be used in applications up to
0.25 Watts in systems such as CDMA, W-CDMA,
PCS, DCS1800, GSM and other analog/digital
wireless communications systems.
Functional Schematic
Negative Control Voltage
The SW-442 is fabricated using a mature 0.5 micron
GaAs PHEMT process. The process features full
passivation for increased performance and
reliability.

3. External DC blocking capacitors are required on all RF ports when using positive voltage control.
4. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.

7. External DC blocking capacitors are required on all RF ports
and GND. GND capacitors can be used with positive control
voltage to resonate lead inductance for improved isolation.
8. If negative control is used, DC blocking capacitors and GND
capacitors are not required.
